Re: Deluxe Edition Armor sets
Deep Space Explorer is crazy good early, even midgame: armor: +5% weapon damage, +15% XP bonus on encounters
Add to it a freebie helmet from andromeda initiative site that beside +10% XP bonus also boosts shields +4% and you're leveling up like crazy.
It's borderline overpowered - if it was upgradeable it'd make it pay2win thing and we don't want that, right?
Lategame, especially if you'll use another overpowered thing (bioconverter aug), if you didn't pick Life Support on lv 6 of Team Support tech tree and don't use one low cooldown spammable tech "spell", you should switch to remnant armor with health/shield regen bonus anyway.
Scavenger armor is basically useless - you'll have tons of $ all the time even without it. It'd be better if the bonus was more materials/minerals while looting.
